Returning a 2015 GMC 2500HD to stock ride height

[Jason Plank]

I recently purchased a 2015 GMC 2500HD (SLE) and the previous owner had Airlift Airbags installed and lifted the front end so the truck appeared level.  I don't like the truck riding so high, it makes it difficult to load. 

 

Here is how the truck looks now:

 

I think it probably has a 2 to 3" lift on it, but I'm not sure if just the front was leveled or if there is a lift in the rear.

Here is the airbag setup:

 

Besides the air bag.  Is there anything here that would raise the height of the rear that should not be there?  Air lift says these airbags will not alter stock ride height.

 

Here is the front suspension setup

 

I think the lower control arm and the shock have a spacer there.  I think that spacer needs to be removed and I need the stock torsion key.

Here is the torsion key:

 

I have no idea if this is stock or not.  I'm think it is NOT stock and low quality due to the amount of surface rust on it.

 

I think if I get the stock torsion keys and remove that spacer between the control arm and the front shock I'll be good to go.  Anything else I'm missing?

Look to see if there is a block under the springs in the rear...the bags look stretched to me...

This is a picture of the bag from below:

 

Not sure if the support for the bag is normal height or not.
